kata-deploy: Add containerd configuration to support kata annotations.

In case of containerd, not all annotations are passed down to the OCI
layer. We need to configure "pod_annotations" field for a runtime class.
This field is a list of annotations that can be passed by Kata as OCI
annotations. Add this as default configuration with kata-deploy.

Fixes: #594
